I would love to have this confirmed by the makers of e.g. navigation software.
It is not clear to me whether you are a data consumer that has this
problem or whether you think they might have a problem.

If you know that there is information about cycleways on separate "osm
ways", why filter them out ?
I wonder how different this is e.g. by filtering out all buildings and
then complaining that house numbers are missing because you can only
process address points.

There is a rule One Feature, One Object in OSM. [1]
It seems to me that anything besides a tag similar to
cycleway=separate is breaking this rule
